Psych, I feel for you. There were times in my life where I figured I could have been labeled ADD or diagnosed with Aspergers... I have a community of friends who have varying degrees of labels including Aspergers and varying forms of autism...
Not sure what to offer as suggestions... what I expect, is you are always in "thought"... so asking you to "think outside of the box", I get you'd have no problem...
That's where I get that the "bed routine" was... maybe could have been better...
I don't know how you could "BE outside the box"... how you can turn off the thinking and just be a little more... spontaneous... maybe practicing by setting up little, safe scenarios and thinking through how "spontaneous" might come through in those times...
